Metabones MB_EF-M43-BT2 overview

  • 1Description

The T Smart Adapter for Canon EF or Canon EF-S Mount Lens to Select Micro Four Thirds-Mount Cameras from Metabones allows a Canon EF or EF-S mount lens to be mounted onto a Micro Four Thirds-mount camera. While doing so, the adapter is designed to support electronic communication between an attached camera and lens. If the lens includes autofocus, image stabilization, as well as camera-controlled aperture functions, this adapter is intended to allow those features to be used. If an attached lens is also capable of generating EXIF metadata when used with a directly compatible camera, the T Smart Adapter is designed to allow that information to be saved along with image files generated with a combination of the lens, a Micro Four Thirds-mount camera, and the adapter.

By enabling camera-controlled aperture functions for a Canon EF or Canon EF-S Mount Lens when used with a Micro Four Thirds-mount camera, program, shutter-priority, aperture-priority, as well as manual modes can be set and used through the camera. Power for these functions is transferred from the camera to the lens, and when manual focusing is preferred with a compatible electronic lens and a Panasonic camera, an integrated jog dial that allows incremental aperture adjustment can be depressed to open the lens's aperture diaphragm to its largest setting. The resulting shallow depth-of-field can then be used to help ensure focus accuracy.

When an image is taken with the T Smart Adapter, a matte black internal coating minimizes the potential for reflections within the adapter barrel, which could otherwise result in unwanted glare within the image.

The T Smart Adapter is constructed from aluminum alloy for durability while minimizing weight. Its mounting rings are made with brass to further prevent wear-and-tear, and a detachable tripod foot is included that features 3/8" threads as well as compatibility with Arca-Swiss tripod heads.

While the T Smart Adapter allows a Canon EF or EF-S mount lens to be mounted onto any Micro Four Thirds-mount camera, any functions that involve electronic communication currently require a Panasonic-brand Micro Four Thirds-mount camera.

  • Allows a Canon EF or EF-S mount lens to be used with a Micro Four Thirds-mount camera
  • Allows third-party, full-frame or APS-C EF-mount lenses to be used with a Micro Four Thirds-mount camera
  • Supports electronic communication between camera and lens to enable autofocus, image stabilization, on-camera aperture control, and EXIF metadata generation when possible
  • Internal coating minimizes reflections within the adapter barrel
  • Integrated jog dial for incremental aperture adjustment and push-button access to lens's widest aperture setting when used with a compatible Panasonic camera
  • Detachable, Arca-Swiss compatible tripod foot with 3/8" threads
  • Aluminum-alloy components for weight reduction
  • Brass mounting rings further prevent wear-and-tear
  • Locking mechanism for secure attachment of lens with push-button release

    Metabones MB_EF-M43-BT2 reviews

    T Smart Adapter for Canon EF or Canon EF-S Mount Lens to Select Micro Four Thirds-Mount Cameras is rated 4.6 out of 5 by 38.
    Rated 3 out of 5 by from Worked great, but watch those tiny screws! The adapter works great, just as described. All functions perfect, except at one point one of the tiny screws came loose and ended up becoming stuck on one of the grooves of the protective lid that comes with it (when you put it in storage). This a week after purchase. It was EXTREMELY hard to dislodge/fix without damaging the adapter, but we got it done, after two days. I had been using the camera outdoors, hiking, so it is possible that some bumping around loosened the screws, but I would check and tighten them just to make sure right after getting it out of the box. OTHERWISE, great product!!!

    Rated 5 out of 5 by from Works better than expected! By mistake I received the T Smart Adapter instead of the Lens Booster 0.71x. (Since I live in Zimbabwe these days I was not able to buy from B&H, my preferred source). After handing over all my other heavy Canon equipment to my son a few years ago when I switched to M43, I was only left with this 1st generation EF 100-400 f/4.5-5.6 L IS and a Canon EOS40D. Maybe it's just the old batteries that haven't been used in 4-5 years but the camera is not switching on... My present camera is the Olympus OM-D E-M5II. I was torn between the new Panasonic 100-400 and the combination Metabones/Canon. Reviews about Metabones are a little mixed especially if you read the older reviews together with the newer reviews without considering the review date... Since I'm not happy at all with my Panasonic 7-14 (purple spots) I considered both items as 'possibly incompatible'. So anyway with the Metabones T Smart Adapter I now have an EF 200-800 f/4.5-5.6. Yes there is a little play on the lens with the Metabones but not worse than with an original Canon 1.4x Extender. It's glassless so no need to worry about scratches! The adapter is beautifully crafted, no plastics to be seen except for the little jog lever. It feels study in the hand.I was prepared to immediately do a software upgrade but that was not necessary (purchase date 20/05/2016). Autofocus is as fast as I could hope for and is spot on. Exif data show the name of the lens and exposure. Thanks to the Olympus IBIS image stabilisation I can now take sharp-sharp pictures handheld at 400mm 1/6 (well, maybe I should say 800mm!)! Don't you agree that that is a photographer's dream-come-true? I add two pictures I took inside in the evening without flash with just a few 2w LED spots in the ceiling. Forget about white balance, subject and artistic value, just look at the sharpness and exposure! Both were taken handheld. I'm 53 and I must admit I'm not as stable as I used to be ;-). So, I'm keeping this T Smart Adapter and won't exchange it for the Speed Booster I originally ordered. Half the price and longer... what more could I wish for here in Africa with all these critters running around...

    Rated 4 out of 5 by from back focus was a little shorter (Redraft) I think Metabones ought to provide a shim to the user as an option. I individual seems back focus was a little shorter than the reference that I bought. Where I have tried in my two GH4 , to focus the scale is a little in front, when the zoom lens used had a focus movement. Therefore, I insert the handmade shim of thickness of 0.01mm to the adapter. Now, this adapter is to use and very comfortable. Quality of Hekisarenchi contained in the case is not so good. I was using the Anex Hex lobe driver T-6 No.6300 Made in JAPAN when you disassemble the mount. Thank you.

    Rated 5 out of 5 by from Terrific Works perfectly. Fast and accurate. Used it with my f2.8 200mm v1 and f5.6 400mm. Just like I had my Canon 70D attached. Used on Pana G7 and Olympus OMD EM5 II.

    Rated 5 out of 5 by from The ultimate addition to my GH4! I am absolutely in love with this speedbooster by Metabones. I have a Sigma art series lens that has an EF mount and I recently upgraded to the GH4. So this adapter not only allowed me to use all functions of my sigma lens on a micro 4/3s mount, but it increased my film quality tremendously! I am more than satisfied with the quality of this product and seriously recommend this to anyone who is still on the fence. 400 dollars did seem steep to me but now that I have used it and have seen what it can do, I don't regret a penny spent, best purchase I've made in a while.

    Rated 5 out of 5 by from Works well with Canon 200mm F2.8L I bought this adapter primarily to add image stabilization to one of my favorite old lenses, the Canon 200mm F2.8L - relatively small, light, and inconspicous compared to it's more popular zoom brethren. Worked great out of the box with my OMD EM-1. Decent autofocus and finally IS! Please note that both adapter and camera had the latest firmware. Also, I have yet to try it on my EP5 or other Canon lenses, but it does what I bought it for and does it well.

    Rated 5 out of 5 by from Excellent product, THE Adapter! Its a dream come through, works 95% with all my vast Canon lens collection. Tested on Lumix GH3 and Olympus EM5 mkII. Tryied with: Old Canon 80-200f.8L Old Canon 85 f1.2L Canon ef100 f2.8 macro Canon 70-300 L Canon 35 f1.4L Canon 24-70 f2.8L DId not Focus with Canon 50 f1.8. Plastic Mount, as clarified on the compatible list on their web site. Highly recomended inspite of the high price.

    Rated 5 out of 5 by from It works! I've tried this with several Canon EF lenses on my OM-D E-M5, and they all auto-focused nicely. Not necessarily as fast as on a Canon camera, but accurately. Even the 100-400 II plus 1.4x III. Now, since I have the Canon 300 f4L IS, I won't need the Olympus 300 f4 Pro; I'm happy indeed.
